UFC's return to St. Louis for the first time since 2018 on Saturday includes six fights on the main card, headlined by a showdown between heavyweight contender Derrick Lewis and 15th-ranked Rodrigo Nascimento.
The main card begins at 7pm ET at Enterprise Centre and will be broadcast by ESPN.
Lewis (27-12 MMA, 18-10 UFC) has recorded 14 knockouts, including finishes of Curtis Blaydes, Alexander Volkov and Marcos Rogerio de Lima.
Meanwhile, the Brazilian Nascimento (11-1, 4-1) emerged from Dana White's Contender Series and enters Saturday on a three-fight win streak.
It's the first headline fight in UFC for the confident Nascimento.
"I have many ways to beat him," he told reporters at Wednesday's media day.
"Putting him on the ground is just one more way. I can strike, I can knock him out. I can finish him, or I can fight all five rounds."
Lewis has held steady as the -165 favourite at BetMGM, where he has been backed by 77 per cent of the money wagered on the fight. Nascimento's odds have shortened slightly from +140 to +135.
Other fights on the main card:
– Joaquin Buckley (18-6 MMA, 8-4 UFC) v Nursulton Ruziboev (34-8-2, 2-0): This welterweight duel sees Buckley trying to build on a three-fight win streak, highlighted by a TKO of Vicente Luque in March. Ruziboev has won his two UFC fights by knockout and TKO to run his overall win streak to 10.
Buckley opened at -165, but has since his odds lengthen a bit to -135 with 80 per cent of the money backing Ruziboev at +110.
– Alonzo Menifield (15-3-1, 8-3-1) v Carlos Ulberg (10-1, 4-1): Menifield has won five consecutive fights, beating the likes of Dustin Jacoby, Jimmy Crute and Misha Cirkunov.
He did have a majority draw against Crute. Ulberg is in his first UFC co-main event, and holds the record for the most strikes landed per minute in UFC light heavyweight history.
The former professional kickboxer has finished each of his past four victories, including over Da-un Jung, Ihor Potieria and Nicolae Negumereanu.
